Abstract: 910,029. Operating tables. U.S.S.R. CENTRAL DESIGN OFFICE OF THE MINISTRY OF PUBLIC HEALTH. May 6, 1960, No. 16086/60. Class 52 (3). [Also in Group XX] In an operating table having a top surface transparent to X-rays, hydraulic rams for height and tilt adjustments are arranged approximately vertically in the supporting pedestal 2. As shown, a spinal section 5 is hinged to an upper leg section 6 and a kidney bridge 7 is interposed between them. Rams 18 which tilt sections 5 and 6 and ram 17 which tilts the whole top surface about its longitudinal axis all have their lower ends mounted on a pillar 19a vertically slidable in the base. A composite ram 20 for vertical adjustment has its lower end mounted directly on the base 1 which houses electric motor 14 driving pump 13, pedal operated pump 15, oil filter 32, reservoir 33, relief valve 30 and a valve having a plunger 28 for operating caster jacks 21. The ram 20 includes telescoping sleeves 20a, 20b, 20d and 20e for connecting rams 17, 18 and 19 to the pumps and reservoir and sleeves 20b and 20c for producing vertical movement of the table by operation of valve plunger 27. Ram 17 (Fig. 4, not shown) is controlled by valve plunger 22 to tilt the table top about its longitudinal axis. Ram 19 is controlled by valve plunger 26 to raise and lower kidney bridge 7. Rams 18 may be operated individually by valve plungers 23 and 25 or in concert, to produce the Trendelenburg position by valve plunger 24. Thus, when plunger 24 is moved to the left, oil is supplied to the upper end of right-hand ram 18 while the top of the left-hand ram 18 is connected with the reservoir 33. The bottoms of the rams 18 are connected together. Valve 29 closes on failure of oil pressure or on pressure produced by an unbalanced load on the table surface. A remote control panel for operating valve plungers 22-28 is connected to the hydraulic system by a flexible cable and may be movably mounted on the table.

Title: Skip detector for viscous layer filmstrip processor
IPC: B05C11/02
Filed: 1965-04-15
Abstract: 1,104,964. Photo-electric layer thickness measurement. EASTMAN KODAK CO. April 15, 1965 [April 15, 1964], No. 16161/65. Heading G1A. A reduction in the thickness of a viscous layer applied to a photographic film during its development is detected by an arrangement shown in Fig. 5 in which infrared light focused by a cylindrical lens 12 to a line across the width of the film only reaches an elongated detector 23 via path 21" as the thickness of the layer at any point across the width of the film falls, to 17 say, the light otherwise being reflected away from the detector along path 21. In another arrangement Fig. 4 (not shown) the angle of incidence of beam 20 is greater than in Fig. 5 so that the beam is always reflected by  the layer or film, a reduction in thickness causing the reflected beam to fall within the field of view of the detector. A second detector 24 compensates for temperature, humidity and ageing of the detectors. The top surface of the layer may be sprayed with a highly reflecting coating.

Title: Improvements relating to electric snap switch mechanism
IPC: H01H5/18
Filed: 1955-06-09
Abstract: 783,014. Snap-action switches. RANCO, Inc. June 9, 1955 [June 21,1954], No. 16585/55. Class 38 (5). A switch comprises a contact arm one end of which is movable between spaced stops, a toggle link pivoted at one end to the arm and at the other end to resilient means, the link also being pivoted between its ends by a pair of spaced fixed pivots. A spring contact arm 25 is mounted at one end by screws 26 on a bracket 13 and carries a contact 27 movable between contacts 28, 29. The toggle link 51 is rigid and has notched ends 52, 53 engaging the arm 25 and the resilient means (a C-spring 50) respectively. The other end of the spring 50 engages a part 55 of an actuator 42 which is mounted at its upper end, Fig. 2, and may be operated by thernally responsive means (not shown). The bracket 13 is connected to a terminal 15 and contacts 28, 29 to terminals 33, 37 respectively. The link 51 passes freely through an aperture in a fixed lug 22, the opposite edges 56, 57 of the aperture providing alternative pivots for the link. With the parts in the Fig. 6 position, the link 51 is biased counterclockwise about pivot 57 by the spring 50 so as to increase the pressure between contacts 27, 29. The link 51 is also biased axially thereof by the spring 50 to increase the contact pressure. Downward movement of the actuator causes the spring 50 to pass through a deadcentre position and the link 51 then moves from pivot 57 to pivot 56 about which it pivots clockwise to move the arm 25 with a snap action. The contact pressure is maintained until the dead-centre position is passed by the axial bias on the link 51. Reverse movement of the actuator causes similar return movement of the contact.

Abstract: 1,187,851. Lattice girders; advancing girders. PEINER MASCHINEN-UND SCRAUBENWERKE A.G. 11 April, 1967, No. 16623/67. Heading E1K. A lattice girder element is adapted to be used on top of a similar element in a mutually inverted relationship to form e.g. an advancing girder unit by having a lower boom comprising a fixed upper member or members 5 or set ot co-planar plates, one at each junction point of the bracing members 2 and 3, and lower detachable member or members 6. The fixed boom may comprise spaced angle section member 7 (Fig. 3, not shown), when the lower member 6 is of channel section. Alternatively, member 5 may be of angle-section (Fig. 4, not shown), T-section (Fig. 5, not shown) or may be a flat member, (Fig. 6, not shown), the above being used with an I-section member 6, a channel-section member 6, and spaced interconnected angle-section members 6 respectively. In the embodiment of Fig. 7 the spaced plates 18 constitute the upper portion with or without a channel-section 16, which may be welded thereto, whilst the channel section 17 constitutes the lower boom, with or without the channel-section 16. When used as a "single height" girder with member or members 6 attached, adjacent girder elements may be connected together by bolt plates 19, 20 at the ends of the upper booms, and turnbuckles 23 at the ends of the lower booms. The girder elements may alternatively be employed upside down (Fig. 11 not shown), when the turnbuckles are replaced by solid boltedon connecting sections. When used as a "double height" girder, the girder units are, e.g. bolted together lower boom to lower boom, Fig. 9 (not shown) employing only the fixed members 5, longitudinally adjacent "lower" boom sections not being connected together. Girders may be connected together side-by-side by cross-bracing which is fixed to laterally-extending plates 35 and 44 adjacent the upper and lower booms respectively.

Title: Improvements relating to quick-acting screw fastening devices
IPC: F16B5/10
Filed: 1950-07-04
Abstract: 692,041. Nuts and bolts; locking. EAKINS, A. H. July 3, 1951 [July 4, 1950], No. 16664/50. Class 89 (i) Relates to quick acting nut and bolt devices in which the bolt is inserted in the nut without rotation and is then engaged by rotating through a fraction of a turn and consists in the provision of a stop device that limits the relative rotation to this fractional turn after which the nut rotates with the bolt, the nut being externally threaded to screw into an outer nut during such continued rotatation. The bolt has flats 18 that pass the threads 19 in the nut 16 that has clearance at 17 for the bolt threads, and is threaded externally to fit the outer nut 10 that is flanged at 11 for anchoring to a part, such as the cowling support on an aircraft, and at 12 to engage with the stop device, which is formed from sheet metal with a flanged hole 24 to fit the bolt and with projections 28 on spring tongues 27 to engage formation 13 on the flange 12 and provide a lock against unintentional unscrewing of the parts. Spring tongues 26 engage cut-away parts in the end of the nut and screw to maintain the formations 28, 13 in engagement. When the bolt is passed axially into the nut 16 it passes also through the hole 24 in the stop device and the latter turns with the bolt as this is given its part turn to engage with the threads 19. When this engagement is completed further rotation relatively to the nut 16 is prevented by contact of lugs 25 with shoulders 22 and the bolt, nut and stop member all rotate together screwing into the outer nut until the required degree of tightening is effected; the lugs 25 engaging in the slots 20 and the projections 28 ratcheting over the formations 13. On unscrewing, the parts again all rotate together until the nut 16 reaches its initial position in the outer nut when further unscrewing is prevented by peened over threads in the outer nut. At this time the lugs 25 are free from the slots 20 and the bolt and stop member make a part turn together till the bolt disengages from the threads 19. A spring 30 is periferally mounted on the outer nut to secure at least a part ejection of the bolt at this stage. Inturned ends of the spring engage in corrugations 14 formed in the flange 11.
